Abstract

La présente invention porte sur un procédé et sur un appareil de commande d'arrêt de climatiseur, ainsi que sur un climatiseur, le procédé comprenant les étapes consistant : à acquérir la température de port d'air de retour actuelle d'un climatiseur ; lorsque la valeur absolue de la différence entre la température de port d'air de retour actuelle et une température préréglée est inférieure à une première valeur de réglage, à augmenter les paramètres de fonctionnement d'un dispositif de réglage du climatiseur passant de premiers paramètres de fonctionnement à des seconds paramètres de fonctionnement ; et lorsque le dispositif de réglage fonctionne selon les seconds paramètres de fonctionnement et que la valeur absolue de la différence est inférieure ou égale à une seconde valeur de réglage, à commander une unité intérieure du climatiseur pour arrêter le fonctionnement, la seconde valeur de réglage étant supérieure ou égale à la première valeur de réglage. Ainsi, une commande d'arrêt n'est mise en œuvre qu'une fois déterminé que la température de chaque position dans la zone active du climatiseur est répartie de manière uniforme, augmentant la précision de l'arrêt d'un climatiseur et augmentant davantage l'intelligence du climatiseur.
